As commented in #53 , sorry i was too busy but finally do this lil contribution.
i guess that fixes, maybe its good make some Exceptions for case of fail, also to add a try catch for Guzzle.

Uuups seems Guzzle is only available for php > 5.5, is that a problem to this repo?

• guzzlehttp/guzzle 6.2.2 requires php >=5.5 -> your PHP version (5.4.45) does not satisfy that requirement.
  • guzzlehttp/guzzle 6.2.1 requires php >=5.5 -> your PHP version (5.4.45) does not satisfy that requirement.
  • guzzlehttp/guzzle 6.2.0 requires php >=5.5.0 -> your PHP version (5.4.45) does not satisfy that requirement.
